如果你喜欢使用CTRL+ALT+UP或CTRL+UP+DOWN复制eclipse样式的行(或块)，下面我发布了用于此目的的宏:

Imports System
Imports EnvDTE
Imports EnvDTE80
Imports System.Diagnostics

Public Module DuplicateLineModule
    Sub DuplicateLineDown()
        Dim selection As TextSelection = DTE.ActiveDocument.Selection
        Dim lineNumber As Integer
        Dim line As String

        If selection.IsEmpty Then
            selection.StartOfLine(0)
            selection.EndOfLine(True)
        Else
            Dim top As Integer = selection.TopLine
            Dim bottom As Integer = selection.BottomLine

            selection.MoveToDisplayColumn(top, 0)
            selection.StartOfLine(0)

            selection.MoveToDisplayColumn(bottom, 0, True)
            selection.EndOfLine(True)
        End If

        lineNumber = selection.TopLine
        line = selection.Text

        selection.MoveToDisplayColumn(selection.BottomLine, 0)
        selection.EndOfLine()
        selection.Insert(vbNewLine & line)
    End Sub
    Sub DuplicateLineUp()
        Dim selection As TextSelection = DTE.ActiveDocument.Selection
        Dim lineNumber As Integer
        Dim line As String

        If selection.IsEmpty Then
            selection.StartOfLine(0)
            selection.EndOfLine(True)
        Else
            Dim top As Integer = selection.TopLine
            Dim bottom As Integer = selection.BottomLine

            selection.MoveToDisplayColumn(top, 0)
            selection.StartOfLine(0)

            selection.MoveToDisplayColumn(bottom, 0, True)
            selection.EndOfLine(True)
        End If

        lineNumber = selection.BottomLine
        line = selection.Text

        selection.MoveToDisplayColumn(selection.BottomLine, 0)
        selection.Insert(vbNewLine & line)
        selection.MoveToDisplayColumn(lineNumber, 0)
    End Sub
End Module

I use application link:AutoHotkey with below code saved in CommentDuplikateSaveClipboard.ahk file. You can edit/remove shortcuts it is easy. I have link to this file "Shortcut to CommentDuplikateSaveClipboard.ahk" in Autostart in windows. This script protect your clipboard. If you are more curious you would add shortcuts to thisable/enable script. I sometimes use very impressive Multi Clipboard script to easy handle with many clips saved on disk and use with CTRL+C,X,V to copy,paste,cut,next,previous,delete this,delete all.

;CommentDuplikateSaveClipboard.ahk

!c:: ; Alt+C === Duplicate Line
^d:: ; Ctrl+D
ClipSaved := ClipboardAll
Send, {END}{SHIFTDOWN}{HOME}{SHIFTUP}{CTRLDOWN}c{CTRLUP}{END}{ENTER}{CTRLDOWN}v{CTRLUP}{HOME}
Clipboard := ClipSaved
ClipSaved =
return

!x:: ; Alt+X === Comment Duplicate Line
ClipSaved := ClipboardAll
Send, {END}{SHIFTDOWN}{HOME}{SHIFTUP}{CTRLDOWN}c{CTRLUP}{LEFT}//{END}{ENTER}{CTRLDOWN}v{CTRLUP}{HOME}
Clipboard := ClipSaved
ClipSaved =
return

!z:: ; Alt+Z === Del uncomment  Line
ClipSaved := ClipboardAll
Send, {END}{SHIFTDOWN}{UP}{END}{SHIFTUP}{DEL}{HOME}{DEL}{DEL}
Clipboard := ClipSaved
ClipSaved =
return

!d:: ; Alt+D === Delete line
Send, {END}{SHIFTDOWN}{UP}{END}{SHIFTUP}{DEL}
return

!s:: ; Alt+S === Swap lines
ClipSaved := ClipboardAll
Send, {END}{SHIFTDOWN}{UP}{END}{SHIFTUP}{CTRLDOWN}x{CTRLUP}{UP}{END}{CTRLDOWN}v{CTRLUP}{HOME}
Clipboard := ClipSaved
ClipSaved =
return

!a:: ; Alt+A === Comment this line, uncomment above
Send, {END}{HOME}//{UP}{HOME}{DEL}{DEL}
return

对于那些在2008年之后还在Visual Studio上查看这个问题的人，一个真正的编辑。副本已添加:

CTRL + E, V Ctrl + d (vs 2017 15.6+)

http://www.jetbrains.com/resharper/

我的故事:开始在一家新公司工作，以前从未使用过Visual Studio。第一件事之一，如何复制线条。设置宏后ReSharper告诉我:你想取代我的快捷方式是:“复制文本”:)

简单的Ctrl + C;Ctrl + V，检查一下 链接。只要你不选择任何文本，当你按Ctrl+C时，这将复制光标所在的行。

Ctrl + D为我工作在VS2012与Resharper。这是Resharper的热键。
